A device for blowing, with the aid of a pressurized fluid, containers from thermoplastic blanks closed in a blow mold including a nozzle whose end is functionally and sealingly connected to the neck of the blank and includes several solenoid valves for selectively connecting the nozzle to the source of a moderately pressurized pre-blowing fluid, to the source of a highly-pressurized blowing fluid and to an exhaust for discharging the pre-blowing/blowing fluid, respectively. The inventive device also includes a body which is mechanically associated with the nozzle, incorporates at least one reception area for receiving a solenoid valve and is selectively connectable to the nozzle.
